AO4414A
N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AO4414A uses advanced trench technology to
provide excellent RDS(ON) and low gate charge. This
device is suitable for use as a load switch or in PWM
applications. The source leads are separated to allow
a Kelvin connection to the source, which may be
used to bypass the source inductance. Standard
Product AO4414A is Pb-free (meets ROHS & Sony
259 specifications). AO4414AL is a Green Product
ordering option. AO4414A and AO4414AL are
electrically identical.

A: The value of RθJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The value in
any given application depends on the user's specific board design. The current rating is based on the t ≤ 10s thermal resistance rating.
B: Repetitive rating, pulse width limited by junction temperature.
C. The R θJA is the sum of the thermal impedence from junction to lead RθJL and lead to ambient.
D. The static characteristics in Figures 1 to 6 are obtained using 80µs pulses, duty cycle 0.5% max.
E. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The SOA curve
provides a single pulse rating.
